The E5612 and E5624 controller-drive trays and the EF560 flash array are shipped with –48-VDC power connector cables if the DC power option is ordered. The –48-VDC power connector cable plugs into the DC power connector on the rear of the controller-drive tray or flash array. The three source wires on the other end of the power connector cable connect the controller-drive tray to centralized DC power plant equipment, typically through a bus bar above the cabinet.
